1) Narxni qachon olsam bo'ladi?
Biz odatda sizning so'rovingizni olganimizdan keyin 24 soat ichida taklif qilamiz. Agar siz narxni olish uchun juda shoshilinch bo'lsangiz, iltimos, bizga qo'ng'iroq qiling yoki elektron pochta orqali xabar bering, shunda biz sizning so'rovingiz ustuvorligini hisobga olamiz.
2) Sizning sifatingizni tekshirish uchun qanday namuna olsam bo'ladi?
Narxni tasdiqlaganingizdan so'ng, sifatimizni tekshirish uchun namunalarni talab qilishingiz mumkin. Agar sizga dizayn va qog'oz sifatini tekshirish uchun shunchaki bo'sh namuna kerak bo'lsa, biz sizga ekspress yukni sotib olishingiz sharti bilan bepul namunani taqdim etamiz.
3) Namuna olishni qancha vaqt kutishim mumkin?
Namuna to'lovini to'laganingizdan va bizga tasdiqlangan fayllarni yuborganingizdan so'ng, namunalar 3-7 kun ichida yetkazib berishga tayyor bo'ladi. Namunalar sizga ekspress orqali yuboriladi va 3-7 ish kunida keladi. Siz o'zingizning ekspress hisobingizdan foydalanishingiz yoki hisobingiz bo'lmasa, bizga oldindan to'lashingiz mumkin.
4) Barcha protsedura qancha vaqt davomida ishlab chiqiladi?
Buyurtma berganingizdan so'ng, ishlab chiqarishni qayta ishlash muddati taxminan 20-25 kun. Hamma narsani tayyorlash uchun bizga 7 kun, keyin ishlab chiqarish uchun 15 kun kerak bo'ladi.
5) Tashish va etkazib berish sanasi haqida nima deyish mumkin?
Odatda biz yuklarni tashish uchun jo'natishdan foydalanamiz. Bu taxminan 7-25 kunni tashkil qiladi. Bu sizning qaysi koutri va portingizga ham bog'liq. Agar siz Osiyo kabi tovarlarni jo'natishingiz kerak bo'lsa, u qisqaroq bo'lishi mumkin. Agar ba'zi favqulodda vaziyatlar mavjud bo'lsa, transport xarajatlarini to'lasangiz, biz yuklarni havo ekspressi orqali jo'natishimiz mumkin.
6) Siz savdo kompaniyasi yoki ishlab chiqaruvchisiz?
Biz professional ishlab chiqaruvchilarmiz. Biz nafaqat asboblar fabrikamizga egamiz, balki sementlangan karbid zavodiga ham egamiz.
7) Sizning zavodingiz qayerda joylashgan?
Biz Xitoyning Xunan provinsiyasining Chjuchjou shahrida, volfram karbid bazasida joylashganmiz.
8) Namuna olishni qancha vaqt kutishim mumkin?
Namuna to'lovini to'laganingizdan va bizga tasdiqlangan fayllarni yuborganingizdan so'ng, namunalar 3-7 kun ichida yetkazib berishga tayyor bo'ladi. Namunalar sizga ekspress orqali yuboriladi va 3-5 ish kunida keladi. Siz o'zingizning ekspress hisobingizdan foydalanishingiz yoki hisobingiz bo'lmasa, bizga oldindan to'lashingiz mumkin.
9) Sizning aktsiyalaringiz haqida nima deyish mumkin?
Bizda ko'p miqdordagi mahsulotlar mavjud, oddiy turlar va o'lchamlar hammasi stokda.
10) Bepul etkazib berish mumkinmi?
Biz bepul yetkazib berish xizmatini taklif qilmaymiz. Agar siz ko'p miqdorda mahsulot sotib olsangiz, chegirmaga ega bo'lishimiz mumkin
